Constants of the quartz-wedge saccharimeter and the specific rotation of sucrose. I. The constants for the 26-gram normal weight
A 1916 National Bureau of Standards technical paper on calibrating the quartz-wedge saccharimeter and measuring the rotation of sucrose solutions, written for laboratory chemists and sugar-testing officials. The seven plates are plotted line graphs on fine ruled grids, with calculated and observed points marked by crosses and circles, plus sectional line drawings of tube mountings and clamps in cutaway hatching, useful as measured diagram and chart stock.
